Ssangyong Construction has secured a contract for the 9th section of the Southern Inland Railway project, valued at 8.065 trillion won. The company holds a 45% stake in the project, amounting to approximately 362.9 billion won. The entire 24.6 km section connecting Goseong and Geoje will be constructed as a tunnel, with 2.9 km utilizing the Shield TBM (Tunnel Boring Machine) method for the underwater railway tunnel.
On October 6, Ssangyong Construction announced that it has won the contract for the 9th section of the Southern Inland Railway, which was commissioned by the Korea National Railway Corporation. The total design cost for the project is 8.0647656 trillion won, with Ssangyong Construction contributing 45%, KCC Construction 15%, and the remaining eight companies each holding 5%. The construction period is set for 60 months from the start date.
The Southern Inland Railway is a national railway project connecting Gimcheon and Geoje. The Korea National Railway Corporation held a groundbreaking ceremony in February and aims to complete the project by 2031. Once operational, the travel time by train from Seoul to Geoje is expected to be reduced to around two hours.
The construction section spans 24.6 km from Goseong-eup in Gyeongsangnam-do to Sadeung-myeon in Geoje City. The entire section is planned to be a tunnel, with 2.9 km passing under the sea using the Shield TBM method. The Shield TBM is a mechanized method where a cylindrical excavator digs the ground while simultaneously installing the tunnel structure.
Ssangyong Construction is currently applying a large-diameter TBM with an outer diameter of 11 meters in the ongoing Pyeongtaek-Osong double-track project, section 5. The company presented its experience in large tunnel construction during the bidding process.
With this contract, Ssangyong Construction will manage three of the 14 sections of the Southern Inland Railway. Earlier this year, it secured contracts for sections 5-2 and 8-2, valued at 232.2 billion won and 211 billion won, respectively.
A representative from Ssangyong Construction stated, “As this is a high-difficulty project that includes the country’s first railway underwater Shield TBM tunnel, we plan to execute the project based on our experience and technology in large-diameter TBM construction.”
